Base64 images are useful when you want to embed everything in a single file: email templates, JSON configs, tiny UI icons, or quick demo pages.

For large blog photos, it’s better to use normal image URLs plus the Image Compressor tool instead of Base64 so pages stay light.

100% local conversion

No images are uploaded to any server; everything happens in this tab.

What is the Base64 string here?: It’s only the encoded data – no data:image/…;base64, prefix. The HTML and CSS outputs already include the full Data URL.
Can I convert many images at once?: Yes. Drop several files and each one will get its own Base64, HTML, and CSS section.
Does this tool change my original files?: No. Files stay on your device. This tool only generates copy-paste snippets and optional .txt files.
